Reducing Ring Spacers

Base Part Number: As shown here, the BASE PART NUMBER defines the Series (three characters), the material (one character), the nominal size, the reduced center hole pipe size RR and the thickness TH. Use a decimal number to indicate the nominal size. Replace RR in the part number with the reduction pipe size in decimals. Then, for thicknesses up to 6”, replace the TH with the decimal thickness. For thickness over 6”, contact factory. Note that the Class (or lb.) designation does not imply a pressure rating. For example, a 3/4” x 1/2” Class 150 PTFE Reducing Ring Spacer x 1” thick would be SRRT-0.75-0.5-1

Options

NPT Threading: For NPT threaded spacers, add to the Base Part Number the suffix NPT.
